Epic equipment, epic moments, and epic animals. The blacktip may not be dangerous, But, if it attacks any large bodied fish nearby, the scent of the fresh blood will attract other sea predators depending on the region in which you are diving in. Have you ever seen the ferocious Tiger Shark? Or the Great White Shark or even the Mako Shark? All sharks require respect, even the sleepy Nurse Sharks. Reminds me of when a scuba diver once thought he could kiss sharks after turning them upside down first, and a Nurse Shark bit his mouth as he attempted to kiss it. People will be people, and sharks will be sharks lol. Life lesson learned I hope for that diver.
